Figure 3.

Reconstructed energy distribution at a few temperatures using Eq. 20 with a window size Δβ=0.02 for the 32×32 Ising model. For comparison, we also show the resulting distributions from averaging energy distributions of two adjacent temperature bins, with the bin size δβ=0.0002. The energy distributions constructed from Eq. 20 with a larger window are more precise than those from simple averages of two adjacent bins.
